Kaiser Carlile was inadvertently struck by a bat during a National Baseball Congress World Series game.

Carlile has been the Liberal Bee Jays' only batboy this summer, team president Nathan McCaffrey said. The Liberal Bee Jays is a summer league baseball team for college players. "He was a part of the team," McCaffrey said in a statement.

McCaffrey, who was at the game, said one of his team's batters accidentally hit Carlile during a warmup swing as the boy was retrieving a bat that had just been used. He said he heard the bat collide with Carlile, who was wearing a helmet. Carlile took three or four steps before he fell as the team rushed to him.

"Just to see him fall, that's what crushes you," said McCaffrey. He said the team wanted to go to the hospital, but the family asked that they not do so.

"I have heard he is still hanging in there," McCaffrey said, adding that it is, "understandable not to want to have 25 guys there when it is so emotional."

The hospital could not provide any other details about Carlile's condition or treatment.

The Bee Jays went on to win the emotional game over the San Diego Waves 12-5 in 13 innings. The National Baseball Congress released a statement calling the incident "an unfortunate and tragic accident. One that saddens us all."

"Donald is going to be as serious as Donald wants to be. And he's going to determine through the depth of his answers and the seriousness of his answers whether he is a serious candidate or he isn't," Christie said in an interview with CNN's Jake Tapper aired Sunday on "State of the Union."

"Anybody can do well for a month in this business, especially if you have talent and personality, and Donald has both those things. Let's see how this goes over the course of time," he said.

The straight-talking New Jersey's governor's presidential hopes largely ride on his confrontational style catching on -- particularly in New Hampshire, the state he's made the focus of his campaign.

But Trump's rise -- a new NBC News/Wall Street Journal poll out Sunday had the real estate mogul leading the Republican presidential field again with 19% support -- has dipped directly into Christie's potential well of support.

Now, Christie is landing around ninth place in national polls, putting him on the edge of missing the 10-person cutoff for Thursday's first GOP debate in Cleveland, hosted by Fox News.

That's fine with him, as long as he makes the cut, Christie said.

"Once you get on the stage it's not going matter whether you're number one or five or 10," he said. "You get the opportunity to make your pitch to the Republican primary voters across America."

He took another shot at Trump during the interview, calling his comment that undocumented immigrants should all be deported, with "the good ones" allowed back in an expedited process, as impractical as Trump's other proposal to build an enormous wall across the U.S.-Mexico border.

"This is like building a 2,000-mile wall across the border that Mexico's going to pay for," he said. "It sounds really good you, pound your chest, but the question is how? How are you going to do it?"

"Mission: Impossible - Rogue Nation" opened to an estimated $56 million at the U.S. box office over the weekend. This total was the second-best "Mission: Impossible" opening ever, just missing out on the $57.8 million of 2000's "Mission: Impossible II."

The Paramount film starring Tom Cruise was good enough to nab the third-best U.S. opening of the star's career, coming in behind "Mission: Impossible II" and 2005's "War of the Worlds."

The spy thriller was also a hit internationally. It made $65 million abroad to bring its global total to $121 million. A good start for a film that cost Paramount $150 million.

"Tom Cruise is the very definition of movie star, but beyond that he is a tireless marketing machine," said Paul Dergarabedian, a box office analyst for Rentrak. "He has essentially written the playbook on how to manifest the perfect combination of star-power based publicity along with producer-based business acumen."

Coming in at a distant second was Warner Bros.'s "Vacation" which earned $14.8 million between Friday and Sunday.

The comedy starring Ed Helms is the fifth installment of the "Vacation" franchise. Since opening on Wednesday, it has made $21.1 million for Warner Bros. (which, like CNN, is owned by Time Warner).

Two big films about small characters, Universal's "Minions" and Marvel's "Ant-Man," battled it out for third place. The $12.6 million of "Ant-Man" just edged out the $12.1 million of "Minions."

And to round out the top five was Sony's "Pixels" with $10.4 million. Box office sales for the Adam Sandler comedy dropped 57% from last week when it took second place.

As the summer box office season nears its end with next week's "Fantastic Four," Hollywood has a lot to be happy about. The 2015 summer box office is up 12.5% overall from last year.

Baltimore drops to 53-51 on season

Daniel Norris took a three-hitter into the eighth inning in his Detroit debut, J.D. Martinez hit a three-run homer and the Tigers beat the Baltimore Orioles 6-1 on Sunday to earn a split of the four-game series.

Norris (2-1) was obtained by the Tigers on Thursday in the deal that sent former Cy Young Award winner David Price to Toronto. Making his seventh career start, the 22-year-old Norris provided a glimpse of his potential against a contender that won seven of its previous eight games.

Norris allowed one run, four hits and a walk in 7 1/3 innings -- the longest outing of his career. The left-hander hadn't started in the majors since April 30, and was 3-10 with a 4.27 ERA for Triple-A Buffalo this season.

On this day, however, Norris was dominant. Assuming Price's spot in the rotation, the rookie proved to be a suitable replacement for the left-handed ace. The only glaring flaw in his performance came in the fourth inning, when Chris Davis homered on a 2-1 pitch.

That was pretty much the extent of the Baltimore offense. After scoring 20 runs in the first three games of the series, the Orioles went quietly against a team that apparently turned the page to next year by dealing Price, closer Joakim Soria and slugger Yeonis Cespedes before Friday's non-waiver trade deadline.

Despite the loss, Baltimore went 5-2 on a homestand that began with a sweep of the Atlanta Braves.
